                            TEXAS PACIFIC LAND TRUST
                          NOTES TO FINANCIAL STATEMENTS
                                  JUNE 30, 2002



(1)      In the opinion of management, the accompanying unaudited financial
         statements contain all adjustments (consisting of only normal recurring
         accruals) necessary to present fairly the financial position of Texas
         Pacific Land Trust (Trust) as of June 30, 2002 and the results of its
         operations for the three and six months ended June 30, 2002 and 2001
         and its cash flows for the six months ended June 30, 2002 and 2001,
         respectively. These financial statements and footnotes included herein
         should be read in conjunction with the Trust's annual financial
         statements as of December 31, 2001 and 2000 and for each of the years
         in the three year period ended December 31, 2001 included in the
         Trust's Form 10-K.

(2)      No value is assigned to the land, unless acquired through foreclosure;
         consequently, no allowance for depletion is computed, and no charge to
         income is made therefore, and no cost is deducted from the proceeds of
         the land sales in computing gain or loss thereon.

(3)      The Sub-shares and the Certificates of Proprietary Interest are freely
         interchangeable in the ratio of one Certificate of Proprietary Interest
         for 600 Sub-shares or 600 Sub-shares for one Certificate of Proprietary
         Interest.

(4)      The Trust's effective Federal income tax rate is less than the 34%
         statutory rate because taxable income is reduced by statutory
         percentage depletion allowed on mineral royalty income.

(5)      The results of operations for the three and six months ended June 30,
         2002 are not necessarily indicative of the results to be expected for
         the full year.

(6)      Cash in excess of daily requirements is invested in money market
         instruments with maturities of ninety days or less. Such investments
         are deemed to be cash equivalents for purposes of the statements of
         cash flows.

         Supplemental cash flow information for the six months ended June 30,
         2002 and 2001 is summarized as follows:

(7)      SFAS No. 131, Disclosures about Segments of an Enterprise and Related
         Information establishes standards for the way public business
         enterprises are to report information about operating segments. SFAS
         No. 131 utilizes the management approach as a basis for identifying
         reportable segments. The management approach is based on the way that
         management organizes the segments within the enterprise for making
         operating decisions and assessing performance. The Trust's management
         views its operations as one segment and believes the only significant
         activity is managing the land which was conveyed to the Trust in 1888.
         Trust management makes decisions about resource allocation and
         performance assessment based on the same financial information
         presented in these financial statements. Managing the land includes
         sales and leases of such land, and the retention of oil and gas
         royalties.

(8)      Effective January 1, 2002, the Trust adopted SFAS No. 144, "Accounting
         for the Impairment of Disposal of Long Lived Assets." SFAS No. 144
         supersedes and amends SFAS No. 121 and the relevant portions of APB
         Opinion No. 30. The adoption of SFAS No. 144 had no impact on the
         financial position, results of operations or cash flows.

                       Analysis of Financial Condition and
                          Results of Operations for the
                                Six Months Ended
                             June 30, 2002 and 2001

                    ----------------------------------------


Results of Operations for Quarter Ended June 30, 2002 Compared to Quarter Ended
June 30, 2001

Earnings per sub-share were $.38 for the second quarter of 2002 compared to $.41
in the second quarter of 2001. Total revenues were $1,744,395 compared to
$1,908,926, a decrease of 8.6%.

Land sales for the second quarter of 2002 were 2,406.65 acres at an average
price of approximately $53 per acre for a total of $128,205. This compares to
1,159 acres at an average price of approximately $70 per acre for a total of
$81,115 in the second quarter of 2001.

Land sales may vary widely from year to year and quarter to quarter. The total
dollar amount, the average price per acre, and the number of acres sold in any
one year or quarter should not be assumed to be indicative of land sales in the
future. The Trust is a passive seller of land; it does not actively solicit
sales of land. The demand for and the sales price of any particular tract of the
Trust's land is influenced by many factors including the national and local
economies, the rate of residential and commercial development in nearby areas,
livestock carrying capacity, and the conditions of the local agricultural
industry which itself is influenced by range conditions and prices for livestock
and other agricultural products. Approximately 99% of the Trust's land is
classified as ranch land and intermingled with other ownerships to form ranching
units. Ranch land sales are, therefore, largely dependent on the actions of the
adjoining landowners.

Rentals, royalties and sundry income amounted to $1,372,109 for the second
quarter of 2002 compared to $1,625,758 for the second quarter of 2001, down
15.6%.

Oil and gas royalty revenue was $909,324 for the second quarter of 2002, down
27.3% compared to the second quarter of 2001. Oil royalty revenue was $612,521,
down 17.8% for the 2002 period. Crude oil production subject to the Trust's
royalty interest was down 5.6% in the second quarter of 2002. The average price
of crude oil was decreased 12.9%. Gas royalty revenue was $296,803 in the second
quarter of 2002, down 41.2% on a volume increase of 11.7% and a price decrease
of 47.3%.

Easement and other sundry income was $281,655 for the second quarter of 2002, up
52.1% from the second quarter of 2001. This income is unpredictable and may vary
greatly from quarter to quarter.

Interest revenue was up 20.8% in the second quarter of 2002 compared to the same
period of 2001. Interest from notes receivable amounted to $231,118, a 25.2%
increase from the 2001 period. Notes receivable for land sold were $10,534,981
as of June 30, 2002, up 41.6% from June 30, 2001, due to installment sales made
in third quarter 2001. Sundry interest was $12,963 for the second quarter of
2002, down 25.9% from the second quarter of 2001. Sundry interest income
fluctuates based on cash on hand for investment, and interest rates on short
term investments.

Taxes, other than Federal income taxes, were down 17.2% due to a decrease in ad
valorem taxes and royalty income production taxes in the second quarter of 2002
compared to the second quarter of 2001.

General and administrative expenses were up less than 1% for the second quarter
of 2002 compared with the same period of 2001.

from the 2001 period.

Taxes, other than Federal income taxes in the first six months of 2002 were down
26.2%. This is due to the decrease in royalty income taxes and ad valorem taxes.

General and administrative expenses for the first six months of 2002 were up
3.1% from the first six months of 2001.

Liquidity and Capital Resources

The Trust's oil and gas royalty revenues, lease rentals and receipts of interest
and principal on notes receivable have generated more than adequate amounts of
cash to meet the Trust's needs and should continue to do so in the predictable
future.
